According to the situation, the expression “configured to” used herein may be used as, for example, the expression “suitable for,” “having the capacity to,” “designed to,” “adapted to,” “made to,” or “capable of”. The term “configured to” must not mean only “specifically designed to” in hardware.

Instead, the expression “a device configured to” may mean that the device is “capable of” operating together with another device or other components. CPU, for example, a “processor configured to perform A, B, and C” may mean a dedicated processor (e.g., an embedded processor) for performing a corresponding operation or a generic-purpose processor (e.g., a central processing unit (CPU) or an application processor) which may perform corresponding operations by executing one or more software programs which are stored in a memory device.

In the description, the word “module” or “unit” refers to a software component, a hardware component, or a combination thereof, which is capable of carrying out at least one function or operation. A plurality of modules or units may be integrated into at least one module and implemented using at least one processor except for those modules or units that need to be implemented in specific hardware.

Various elements and regions in the drawings are schematically drawn. Therefore, the technical concept of the disclosure is not limited by a relative size or spacing drawn in the accompanying drawings.

Various embodiments described above may be implemented in a computer or similar device-readable recording medium using software, hardware, or a combination thereof. In the case of implementation by hardware, embodiments described in this disclosure may be implemented using at least one of application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, microcontrollers, microprocessors, electronic units performing other functions. In some cases, embodiments described in this disclosure may be implemented by the processor 160 itself. In the case of software implementation, embodiments such as procedures and functions described in this disclosure may be implemented as separate software modules. Each of the software modules may perform one or more functions and operations described in this disclosure.

The image processing method according to various embodiments described above may be stored in a non-transitory readable medium. Such a non-transitory readable medium may be installed and used in a variety of devices.

Such a non-transitory readable medium is not a medium for storing data for a short time such as a register, cache or memory, but refers to a medium that semi-permanently stores data and may be read by a device. Specifically, programs for performing various methods described above may be stored in the non-transitory readable medium may include a CD, DVD, hard disk, Blu-ray disc, USB, memory card, ROM, and the like, and provided.

According to embodiments, the methods according to various embodiments disclosure in this document may be included in a computer program product and provided. The computer program product may be traded as goods between a seller and a purchaser. The computer program product may be distributed as a device-readable storage medium (e.g., compact disk read only memory (CD-ROM)) or online through an application store (e.g., play store™). In the case of online distribution, at least part of the computer program product may be temporarily stored or temporarily created in a storage medium such as a server of a manufacturer, a server of an application store, or a memory of a relay server.

Hereinabove, the embodiment of the disclosure have been described but the disclosure is not limited to the specific embodiment and may be variously modified by a person skilled in the art to which the disclosure pertains without departing from the scope of the disclosure as claimed in the appended claims and such modifications should not be individually understood from technical concepts or prospects of the disclosure. 

What is claimed is:
 1. An electronic apparatus comprising: a display; a motor configured to rotate the display; a memory configured to store at least one instruction; and a processor configured to execute the at least one instruction stored in the memory to control the electronic apparatus and to control the display to operate in a display mode among a horizontal display mode and a vertical display mode, wherein the processor is configured to: control the display to display at least one horizontal UI item preferentially left-side or upper-side within a group of a plurality of UI items while the electronic apparatus operates in the horizontal display mode and to display at least one vertical UI item preferentially left-side or upper-side within a group of a plurality of UI items while the electronic apparatus operates in the vertical display mode.
 2. The electronic apparatus as claimed in claim 1, further comprising: an input unit configured to receive a user command, wherein the apparatus is configured to rotate the display by driving the motor according to a user command input through the input unit.
 3. The electronic apparatus as claimed in claim 1, wherein the plurality of UI items include at least one of an image content, a document or an image.
 4. The electronic apparatus as claimed in claim 1, wherein the horizontal UI item is a UI item having an aspect ratio in which horizontal length is longer than vertical length, and wherein the vertical UI item is a UI item having an aspect ratio in which vertical length is longer than the horizontal length.
 5. The electronic apparatus as claimed in claim 1, wherein the processor is configured to: control the display to display additional text related to a corresponding UI item at a lower region of each of the plurality of UI items while the electronic apparatus operates in the horizontal display mode; and control the display to display additional text related to a corresponding UI item at a right side region of each of the plurality of UI items while the electronic apparatus operates in the vertical display mode.
 6. A method of controlling an electronic apparatus that is rotatable and operates in a display mode among a horizontal display mode and a vertical display mode, the method comprising: displaying at least one horizontal UI item preferentially left-side or upper-side within a group of a plurality of UI items while the electronic apparatus operates in the horizontal display mode; and displaying at least one vertical UI item preferentially left-side or upper-side within a group of a plurality of UI items while the electronic apparatus operates in the vertical display mode.
 7. The method as claimed in claim 6, wherein the electronic apparatus is configured to operate in one of the horizontal display mode or the vertical display mode by rotating a display by driving a motor included in the electronic apparatus according to a user command input through an input unit.
 8. The method as claimed in claim 6, wherein the plurality of UI items include at least one of an image content, a document or an image.
 9. The method as claimed in claim 6, wherein the horizontal UI item is a UI item having an aspect ratio in which horizontal length is longer than vertical length, and wherein the vertical UI item is a UI item having an aspect ratio in which vertical length is longer than the horizontal length.
 10. The method as claimed in claim 6, wherein the displaying the at least one horizontal UI item preferentially comprises displaying additional text related to a corresponding UI item at a lower region of each of the plurality of UI items while the electronic apparatus operates in the horizontal display mode, and wherein the displaying the at least one vertical UI item preferentially comprises displaying additional text related to a corresponding UI item at a right side region of each of the plurality of UI items while the electronic apparatus operates in the vertical display mode.
